HELP ASAP!!! WILL MARK BRAINLIEST

Mathematics
1 answer:
Nitella [24]3 years ago
5 0

Answer:

  • 50x⁴ - 20x² + 1 = 0

1. <u>Quadratic form</u>

  • 50(x²)² - 20x² + 1 = 0

2. <u>U is</u>

  • x² = u

3. <u>U- substitution</u>

  • 50u² - 20u + 1 = 0

4. <u>Find the discriminant and identify roots</u>

  • d = (-20)² - 4*1*50 = 200
  • u = (20 ± √200)/100
  • u = (2 ± √2)/10

<u>Solve for x</u>

  • x² = (2 ± √2)/10
  • x = ± √((2 ± √2)/10), four roots

What does it mean if a check was skipped on a bank statement?
hoa [83]
The <u>correct answer</u> is:

The check has not been cashed yet.

Explanation:

When you receive your bank statements, all of the transactions that have been processed are listed.  This includes deposits, debits and checks.

All transactions are usually listed in order of the date of transaction.  Additionally, the checks are usually listed at the bottom of the statement.

If there is a gap between check numbers that you have written, it means that the missing checks have not been processed. This means that they have not been cashed or deposited.

Sheila multiplier 62.5 by 4.08. What should have been her answer if she quickly rounded the numbers before multiplying?
kozerog [31]
The answer would be 252. Here’s why:

You always round up when it’s five (half) or above. 4 or Lower will round it down. In our question here, 62.5 would be rounded up, and 4.08 will be rounded down. This lets us rewrite the question as 63 times 4, and we get 252.

Hope this helps!

Need help solving the equation, trying to figure whether I multiply or divide.​
USPshnik [31]

Answer:

m∠B = 43°

b = 26.1

c = 38.3

Step-by-step explanation:

By applying triangle sum in the given triangle,

47° + 90° + m∠B = 180°

137° + m∠B = 180°

m∠B = 43°

By applying sine ratio to the angle measuring 47°.

sin(47°) = \frac{\text{Opposite side}}{\text{Hypotenuse}}

            = \frac{28}{c}

c = \frac{28}{\text{sin}(47^{\circ})}

c = 38.28

c ≈ 38.3

By applying cosine rule,

cos(47°) = \frac{\text{Adjacent side}}{\text{Hypotenuse}}

             = \frac{b}{c}

             = \frac{b}{38.3}

b = 38.3[cos(47°)]

b = 26.1
